SPECIFICATION forming part of Letters Patent No. 789,534, dated May 9, 1905.

Application tiled August 22, 1904. Serial No. 221,746.

To @ZZ who/nf it '11m/y concern:

Be it known that I, Ronun'r T. GILLusrm, a citizen of the United States, residing at Rochester, in the county of Beaver and State oi' Pennsylvania, have invented certain new and useful Improvements in luk-lfVells, oi which the Vfollowing is a specilication, reference being had thel'ein to the accom panying drawings, forming part ot' this specilication, in which-- Figure 1 is a vertical sectional view of my improved ink-well. Fig. 2 is a similar view showing a modilied construction provided with two oppositely-located delivery-necks. Fig. 3 is asimilar sectional view showing a verticallyarranged delivery-neck. Fig. i. is a horizontal section on the line IV 1V oi' Fig. 3. Fig.

is a similar sectional view showing a construction provided with a removable cover for the entire area ol the reservoir. Fig'. G is a similar view showing the delivery-neck provided with an adjustable cover. Fig. 7 is a partial detail sectional View of the same construction, showing the cover raised and iixed in open position. Fig. 8 is a perspective detail view of the spring-controlled cover for the neck. Figs. 9, 10, and 11 are detail views in perspective ot' different 'l'orms ot' neckfloats.

My invention consists otl improvements in the class of ink-wells oi the class wherein a main reservoir is provided ttor the ink and a laterally-disposed delivery-neck is arranged in communication with the reservoir at its base and provided with means for covering the ink. The covering means consists oi an automatically-adjustable llloat adapted to rest upon the surface o'll the ink in the neck and provided with a central reduced cavity whereby the ink is delivered in limited quantity to the pen-point merely by insertion.

Referring to the drawings, 2 is the main ink well body, preferably rectangular in term, althougli it may be circular or otherwise formed, as desired, provided with a res ervoir-cavity, adapted to contain the main body otl ink and provided with a removable cover l. At one side or in front of the well is an independent neck-chamber 5, communieating' with the main reservoir at the bottom through a port-opening 6, so that the ink in the reservoir and neck will always be maintained at the same level. The neck preterably inclines lforwardly, as shown, at any suitable angle, to Facilitate insertion of the pen-point, and in the neck is mounted a 'lloat 7, oi" cork or other suitable buoyant material, iitting freely within the neck-chamber to Yfacilitate easy movement. The tloat is provided with a central cavity or channel 8, terminating at the top in an outwardly-laring orii'ice 9 ot sutiicient size to admit the point of the pen, the channel 8 being so reduced that the tip ot' the pen only enters it. This construction is ot advantage in indicating' to the operator not only when the tip has been inserted into the channel, but also indicating the moment ot' contact with the lloat, so as to gage the downward pressure thereotI in order to su'iiiciently submerge the pen-point.

For the purpose ot preventing the `iloat `from rotating the neck-chamber is pre terably made square or of other suitable vlorm in crosssection, this construction being' otl advantage in always maintaining' the long lip oi' the iloat in front when used with a slanting neck having a horizontal top, as in Figs. Q, 5, and 6. Otherwise, however, the l'loat may be made to correspond with the upper terminal of the neck il extended as in Fig. 1, and the float and neck may also be made circular in ilform, as indicated in Fig. l1.

For the purpose et simplifying the construction of the well when made ot' glass or other material by means ot' plunger mechanism the form shown in Figs. 5 and (5 may be employed, wherein the 'full area ot the reservoir is continued te the top, and a cover lO of corresponding area, provided with interi'itting lips 11, is used. In other respects, however, the construction and mode ol operation are the same. For the purpose ol covering the top otl the neck 1 employ a cap l2, pivotally connected at 13 with a base l-I, cemented or otherwise secured to the top oi the well-body, as shown. A spring' l5 is secured underneath said base in a cavity formed in the body of the well, which presses upwardly against a double 'l'iat-liaced shoulder 16, lforming a portion ot' the cover, so as to exert pressure positively against said shoulder to hold the cap down in position or upwardly, as shown in Figs. 6 and 7, respectively.

In Fig. 2 the well is shown provided with two oppositely-ari-anged necks, adapting it to use on a double desk, each neck communicating with the common well 3/ and being provided with independent fioats, as shown.

The operation will be readily understood from the foregoing description.

The device is very compact and simple in construction, the indicating-float is of great assistance to the operator in filling the pen, the inclination of the neck allows the pen to be inserted in a natural direction, while the iioat also covers the ink and practically prevents evaporation or contamination of the ink.

The well is especially adapted to incorporation with any suitable receiving or holding receptacle havingI openings or apertures in the front or side-as, for instance, a desk-drawer through which the pen may be inserted to reach the neck. The lioat in such cases immediately indicates the depth to which the pen should be inserted.

Changes or variations may be made by the skilled mechanic in the design, proportions, or other details of the invention; but all such are to be included within the scope of the following claims.

lVhat 1 claim isl. An ink-well provided with a main reservoir-chamber, a neck-chamber having a pol ygonal cross-area communicating with the reservoir-chamber at the bottom, and a freelymovable float fitting loosely in the neck-chamber, provided with a reduced central cavity Haring outwardly at the top, substantially as set forth.

2. An ink-well consisting of an integral body portion of suitable material provided with a main reservoir having a removable top,

an inclined neck provided with a suppl y-chamber communicating with the main reservoir at the bottom, and a freely-movable oat mounted in the neck-chamber and provided with a central reduced opening and a flaring' pen-insertion opening at the top, substantially as set forth.

3. An ink-well consisting of an integral body portion of suitable material provided with a main reservoir having a removable top, an inclined neck provided with a su ppl y-chamber communicating with the main reservoir at the bottom, and a freely-movable float mounted in the neck-chamber and provided with a central reduced opening and a Haring pen-insertion opening at the top, the neck-chamber and float being so formed in cross-section as to prevent rotation of the float, substantially as set forth. Y

Llc. Thecombination with an ink-well having a main reservoir and an inclined neck-chamber communicating therewith at the bottom with a perforated iioat mounted in the neckchambcr: of a spring-controlled cover for the neck-chamber, substantially as set forth.

5. The combination with an ink-well having a main reservoir and an inclined neck-chamber communicating therewith at the bottom with a perforated float mounted in the neckchamber: of a base secured to the ink-well body and provided with a pressure-spring, and a cover for the neck-chamber pivoted thereto and provided with spring-bearing shoulders adapted to make contact with the spring, substantially as set forth.

In testimony whereof I atlix my signature in presence of two witnesses.
